(a) Delegated, approved, or authorized activities. A Tribe or Intertribal Consortium may use Performance Partnership Grant funds to carry out EPA-delegated, EPA-approved, or EPA-authorized activities, such as permitting and primary enforcement responsibility only if the Tribe or each member of the Intertribal Consortium receives from the Regional Administrator the delegations, approvals, or authorizations to conduct such activities.

(b) Other program activities. Except for the limitation in paragraph (a) of this section, a Tribe or Intertribal Consortium may use Performance Partnership Grant funds for any activity that is eligible under the environmental programs listed in § 35.501(a) of this subpart, as determined by the Regional Administrator. If an applicant proposes a Performance Partnership Grant work plan that differs significantly from any of the proposed work plans approved for funding that the applicant now proposes to move into a Performance Partnership Grant, the Regional Administrator must consult with the appropriate National Program Managers before agreeing to the Performance Partnership Grant work plan. National Program Managers may expressly waive or modify this requirement for consultation in national program guidance. National Program Managers also may define in national program guidance “significant” differences from a work plan submitted with a Tribe's or a Consortium's application for funds.
